Application filed August 7, 1916. Serial No- 113,522. 7

To all whom it may concern:

Be it known that I, JOHN J BUTLER, a

citizen of the United States, residing at Norfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Range-Boilers, of which the following is a specification.

My invention relates to range boilers and has for an object the provision of simple, reliable and inexpensive means for collecting and discharging sediment to the end cold water supply pipe against the sides of the boiler. With these and other objects in view, the nature, characteristic features and scope of the invention will more readily be understood from the following description taken in connection with the accompanying drawings forming a part hereof, wherein Figure 1 is a sectional elevational view of a range boiler embodying features of my invention; and

Fig. 2 is a section on line 22 of Fig. 1.

The range boiler 5 is provided with a cone shape bottom 6 and in proximity thereto with a cone shape baffle or partition 7, the space between the two constituting a trap or sediment settling or collecting chamber 8. the member 7 being provided with a readily-detachable two-way fitting 9, which connects the boiler proper with the chamber 8.

The two-way fitting is important and ad" vantageous because if one branch is fouled by an accumulation of sediment on one side of the trap the other branch'will be free to perform its function. I

The cold water supply pipe 10 extends to about half-way of the axis of the cone shape baffle 7 and is equipped with an angularly disposed multi-point jet discharge nozzle or Copies of this patent may be obtained for Specification of Letters Batent. I Patented Mar. 5, 1918.

spray ll. The latter discharges onto the: baflie and water and suspended matters flow via the fitting 9 into the settling chamber or trap 8. The pipe 12 which supplies water from the boiler to the waterback '14: has its inlet 13 disposed above the nozzle 11 and hence in a clear water zone. Pipe 12 is provided with a valve or cut-ofi 15. 16 indicates the hot water return, and 17 the usual hot water circulating pipe.

18 is a pipe lineleading from the bottom of the boiler to, for example, a sink 19,

whereby it is possible to constantly use the water in the boiler and thus keep the same clear of sediment. Or, if desired,'any accu mulations of sediment in. the collecting chamber may spigot 20.

The spray pipe 10 is braced by a spider form of support 21. Bythis arrangement it is prevented from vibrating and striking against the sides of 'the boiler, whereby humming and other objectionable noises are obviated. i

A structure of the type recited, compris waterback having a cold water connection extending upwardly through the double bot tom and provided with a cutoff, a hot water return, and a hot water circulating pipe.

In testimony whereof I affix my signature in the presence of two witnesses.
